Chowhounds agree that duck fat is one of the tastiest things you can cook with. Here are some favorite ways to use it:
Potatoes fried or roasted in duck fat are just about perfect. Duck fat is also great for cooking grilled cheese, frying eggs, and sauteing spinach or chard.
Rub duck fat over a whole chicken or turkey before roasting. It gives a richer flavor than butter, with more depth, says Kishari.
Caramelize onions very slowly in duck fat and you are in for a sublime treat, promises Sean Dell. Use the onions in a tart, or mixed with some potatoes.
Slow poach high-fat fish such as salmon in duck fat at a low temperature, for one of the richest, most succulent pieces of fish you’ll ever have, recommends HeelsSoxHound.
